Use cofunction identities and trig identities to find indicated trig functions

The video tutorial explains how to determine the cosecant of 30 degrees using the reciprocal identities of sine and cosecant. It begins by introducing the relationship between sine and cosecant, explaining that they are reciprocals. The tutorial then demonstrates how to apply this knowledge to find the cosecant of 30 degrees, given that the sine of 30 degrees is 1/2. By understanding that sine is opposite over hypotenuse and cosecant is hypotenuse over opposite, the video shows that the cosecant of 30 degrees is 2.
